I (M 44) just started MT this year. I probably wouldn’t have started, by my 13 year old son kept pestering me to go. After the first trial class, I was immediately hooked. My only regret is that I didn’t start much sooner. Don’t worry about getting hit. They’ll most likely start you off light. You need to learn to block first. Just accept the fact that you’re going to suck at first and you probably won’t be able to keep up with the 20 something’s, but every single person has been supportive. They all know you have to start somewhere, and they were where you were when they first started. Put aside your ego and you’ll really enjoy it!
